I'm using monoprice's RCA cables all in wall for both my subs. But when they come to the back of their 7.2 wall plate, the back is threaded and the front is not. So I'm using connectors and it makes for a very long subwoofer connection to the back. Are there any 7.2 wall plates that plug straight in on the back and front?
Also, 1 of my sub when I push on the connection at the back, it makes a humming noise. Only when I push on it does it make this noise. The other sub does not. Any opinions besides the obvious "don't push on the connection"
I personally don't know of any. The reason most or all of the wall plats use RCA front and F screw connection on the back is that you run coax cable the same stuff as you do for cable TV behind the walls for the subs. This is cheaper than RCA cables. I used the monoprice 7.2 wall plate and ran coax "TV" cable in my walls for my subs. Then just RCA cable from receiver to wall plate then RCA from 2nd wall plate at sub to the sub.
I didn't know about using regular coax cable and simply bought long RCA cables from Monoprice instead and ran it in my walls. But with the RCA and F connectors, the thing is quite long and I had to push quite hard to get the wall plate in since the space behind it is limited for such a long connection. I'm hoping it doesn't damage the cables.
